MACHINE FOR CARBONATING AND DISPENSING LIQUIDS.

Specification of Letters Patent.

Patented Apr. 15, 1913.

Application filed January 8, 1912. Serial No. 669,954.

T 0 all whom @'25 may concern: Be it known that I, HENRY PEIN, a citizeof the United States, and a resident of J ersey City, in the county ofHudson, State of New Jersey, have Ainvented a certain new and usefulMachine for Carbonating and is a specification.

My invention relates to a machine for carbonating liquid automaticallyand for dispensing the liquid, and'though my invention in its entiretyaccomplishes a very important result, due to the various branches of thewhole acting in correlation, nevertheless some parts of my invention maybe used independently in other relationships.

I will describe my invention in its full combination and embodiment, asconstructed for both carbonating a liquid and automatically dispensingthe same.

Under the present invention it is possible to make a machine which willautomatically erly eommingling carbonio gas with the water, to form anaerated beverage; and which will automatically dispense the liquid indesired and predetermined equal quantities, preserving the liquid in theaerated condition until dispensed. The machine is adapt? ed to becontrolled by means of a coin controlled mechanism, and in my copendingapplication serially numbered 669,953 and led concurrently herewith, Ihave shown a coin mechanism which may be very successfully used inconnection with the present machine, and which is made the subjectmatter ofra separate application in order to comply with the rules ofpractice of the U. S. Patent Office. In t-he present case I have shownthe coin mechanism of my said copending case applied to operate thepresent machine but it is to be understood that other than coinmechanism may be employed.

The object of my present invention is to overcome the objections offormer constructions by providing means which will be mechanicallyoperated for supplying liquid to the reservoir, as distinguished frommeans operated or controlled by the condition or weight of the liquiditself. In the fullest embodiment of my invention the supply of liquidto the reservoir is caused mechanically by the operat-ion of thedispensing mechanism by which the operation of the machine 'ismechanically initiated. In this manner the supply to the reservoir ismade positive and it will be operative as long as the maf chine isoperative.

Dispensing Liquids, of which the following i If the machine is connectedwith a conl tinuous source of supply, liquid will be supplied to themachine as long as it is used to l' dispense drinks, and a point is notreached where the supplying means requires reseti ting. By connectingthe supplying mechanism to be operatedl periodically and mechanically bythe mechanism which controls the operation of the machine, the supply tothe reservoir can be regulated to correspond 4with the rate of depletionin the reservoir f as the liquid is dispensed therefrom. In other words,there will be a relationship bejtween the amount furnished to thereservoir and that dispensed by the machine, and mechanically andproperly regulated.

carbonate a liquid, such as water, by prop- Another object of myinvention is to accomplish the above objects in a machine in which acharged liquid is used and more especially in a machine in which theliquid ,is therein charged with a gas so that an l automatic vendingmachine for such liquids Amay be had.` In the preferred form of my iinventionI introduce the liquid and the gas in 'a primary receptacle andfrom this they lare passed into the reservoir, from whence fthe aeratedliquid is dispensed. The entry fof the liquid and gas into the primaryreceptacle is preferably controlled mechani- :cally from the mechanismwhich controls the operation of the machine. I also am able to use theforce of the incoming gas to project the liquid from the primaryreceptacle into the reservoir. I am also able to let off the residuum ofgas and air in the primary receptacle after it has been discharged ofits liquid so that a new supply of water may be received therein and afresh supply of gas as well, and this without depreciating the mixturein the reservoir.

Another object of my invention is to provide a machine which will notdrip, and

wherein air will not enter into any part occupied by the gas orcarbonated liquid, even though the machine stands unused forcomparatively long periods.

Another object of my invent-ion is to construct a machine having theabove advantages and in which the liquid may be independently andsimultaneously, or individually discharged at different points, such asfrom several faucets on the same machine, taking the liquid from thecommon reservoir.

Another object is to construct the dispensing devices so that indispensing from several faucets, the mechanism will be reduced to simpleconstruction.

Another' object of my invention is to operate a common reservoir fillingdevice in connection with 'the several dispensing devices.

Vith these and other objects in view, I haveembodied my invention in aconcrete structure which embodies what I consider to be the form of myinvent-ion.

In the drawings forming a part of this application, Figure 1, is anelevation of a machine embodying my invention, in which cert-ain partsare shown in section, Fig. 2, is a plan view in which certain duplicatepart-s are omitted; and is taken on the line 2 2 of Fig. 1, Fig. 3, isa. sectional view showing parts of the mechanism for operating therefilling device, Fig. 4, is a cross section taken on the line 4 4 ofFig. 3, looking in the direction of the arrows, Fig. 5, is a sectionalview, taken on the line 5 5 of Fig. 3, looking in the direction of thearrows, Fig. 6, is a sectional view of the valve which controls thesupply of liquid to the primary receptacles and the reservoir, Fig. 7,is an elevat-ion of the valve removed from its casing, Fig. 8, is asimilar view from a different point, Fig. 9, is a sectional view showingthe valve by which the primary liquid receptacles are relieved of theirpressure, Fig. 10, is a. section thereof, taken on the line 10 10 ofFig. 9, looking in the direction of the arrows, Fig. 11, is a' plan viewof the parts controlling` the supply of gas to the primary receptaclesand the discharge of residual gas preceding the refilling of the primaryreceptacle with water, Fig. 12, is an elevation ofthe same, and Fig. 13`is a sectional view of one 0f the valves.

In adaptingmy invention to a machine in which several faucets dispenseliquid from a common reservoir I prefer to provide two primary liquidreceptacles for supplying the liquid to the reservoir and to operatethem so that while one is being filled the other can be emptying itscontents into the reservoir. I will describe my invention as embodied insuch a structure, although it will be vobvious that a single primaryreceptacle may be used.

In the drawings I have shown my apparatus placed in and on a cabinet 1,whereby the apparatus may be'used as a public liquid dispensing machine,but such arrangement is only preferred and may be departed from withoutchanging the nature of the apparatus.

I have shown a reservoir 2, which consists merely of ametal tanksuitable for containing a liquid and a gas under pressure, which tank isnot of itself, necessarily of special construction. The liquid ispreferably admitted to the top of the tank and withdrawn from thebottom. I admit the liquid at the port 3, and it strikes against theplate 4, which causes it to spray; and in thus breaking the stream intoa spray within the part of the reservoir usually occupied by the gas, amore complete commingling of the gas and water is accomplished. Thewater is taken from the reservoir through the pipe 5, which runs down tonear the bottom of the reservoir and through this pipe 5, the aeratedliquid is taken to a cooling coil 7, arranged in `an ice chamber 8, atthe top of the cabinet.

I have arranged two primary receptacles 9v and 10, which alternatelydischarge a regular quantity of water into the reservoir. In a casing11, I have arranged a valve, 25, which is automatically operated whenthe vending apparatus is operated, and it controls the supply ofliquid., The valve casing 11, is provided with various connections andports, with which latter, ports in the valve are adapted to register. Ihave provided a filter 13, consisting of two spherical halves 14 and 15,which are clamped tightly together by bolts 17, with a piece of felt 16,between them. The water or other liquid is received through a pipe 19,from the continuous source of supply, usually from a water main. Inpassing through the sheet of felt, the water is filtered and cleansed,leaving a residue which can be removed by taking ofi' the upper half ofthe filter.

The pipe 19, is coupled with a connection 23, on the valve body 11,whereby the liquid is brought into the valve body through a port 24, inthe valve. The valve 25, has a number of ports extending in variousdirections and one of these ports 24, extends through the valve,preferably transversely, and connects with an L shape outlet'port 26. Ateach half revolution of the valve, one end of the port 24, is broughtinto register with the inlet pipe 19, or rather the bore thereof, andthe extension 26, of this port is at the same time brought into registerwith either the port 27 of a connection 28, or the port 29, 0f aconnection 30, arranged opposite each other on the valve body. A pipe31, is coupled with the connection 28, and connects at the point 32,with the upper part of the primary receptacle 10. Similarly a pipe 33,is coupled with the connection 30, and at 34, it connects with the upperpart of the primary receptacle 9. From this it will be apparent that atevery half turn of the valve, the port 24, 26, will connect the watersupply, first with t-he receptacle 10, and then with the receptacle 9,thereby alternately supplying each with water, or other liquid, to becarbonated and dispensed.

The valve 25, is also provided with an angular port 52, one end of whichtravels on the horizontal line of a port 53, in con` nection 54, and aport 55, in the connection 56, and the other end extends to the bottomof the valve and opens into the pipe 3, and therefore discharges intothe reservoir. To the connection 56, is coupled a pipe 57, which iscoupled to the receptacle 10 and runs to the bottom thereof, so that thereceptacle will be completely drained. Likewise a pipe 58, is coupled tothe Connection 54, and it is connected with the receptacle 9, andextends to the bottom thereof, so as to completely drain the latter. Atevery half turn of the valve, the port 52, connects first the port 55,with the reservoir, thereby allowing the receptacle 10, to empty intothe reservoir and then it connects the port 53, with the reservoir andtherefore allows the receptacle 9, to empty into the reservoir.

The ports 26, and 52, are oppositely arranged, so that when one primaryreceptacle is receiving water the other is discharging its liquid.

The receptacles 9 and 10 may be provided with gages 59, and 60,respectively, if desired, to show the depth of liquid in the receptaclesthough such are not a necessity.

In the heads 48, and 51, on the tops of the primary receptacles Iprovide valves to permit the discharge of the air or gas in the primaryreceptacles, just before and during the time the liquid is running intothem, to permit the receptacles to be lled with liquid; and these valvesare adapted to be closed by the liquid when it reaches a predeterminedheight, preferably when the receptacles are entirely filled. Both suchvalves are alike so that a description of one will answer for both. Thecasings of these valves are numbered 61 and 62, in Fig. 1, and thedetails thereof, are shown in Figs.

y '9 and 10. The casing 62, is hollow and is formed with a shoulder 68,on which a float 64, may rest and at the top it is provided with an openvent 67, surrounded by a` valve seat 68. The float 64, is provided withrods 65, on its exterior', which space the float from the interior wallof the casing, 62, to allo-w the exhaust from the receptacle 9, or 10 asthe case may be, to pass around the float and through the vent 67. Avalve 66, is carried on the top of the float,`which seats on the valveseat 68, and shuts olf the vent. The oat may rest on the shoulder 63,while the receptacle to which the valve is connect ed is being filledwith liquid and when the liquid reaches the fioat it lifts the latterand seats the valve 66, and prevents the liquid in the receptacle fromoverliowing, by closing the vent 67.

In Figs. 11 and 12, I have shown the devices for supplying the gasautomatically, at definite periods, to the primary receptacles; and forrelieving any residual pressure just previous to the admission of theliquid. I have made this branch of the apparatus automatic, that is,controlled by the manually operated branch of the devi-ce so that thegas will be controlled according to the aerated liquid dispensed. I havearranged this branch of the machine, so that the operations will beproperly timed relative to the periodical charging of the primaryreceptacles with liquid. I prefer therefore to control the gas supplyand liquid supply through the same operating mechanism.

I have found that where ground in valves are used to control the supplyof gas to the reservoir it is impossible to obtain a sufliciently tightmetal to metal contact between the valve and its seat, or casing, toprevent gas from passing when the valve is closed, unless the valve isarranged so tight in its casing as to make it practically impossible tooperate. The result, where gro-und in valves have been used, has been acontinual leakage of gas, resulting in a leakage at the dispensingfaucets, which aside from the loss of gas causes a breaking down of theaerated liquid. In addition to this there was the additionaldisadvantage that gas vpassing the valve backed into the water main from.which the liquid supply of the ,machine was obtained, causing manydifiiculties. It is feasible to use the ground in valve for the watersupply, but not for the gas supply; and I therefore prefer to useseparate valve systems for the water and gas. For the gas I use valveswherein pack ing is used, wherein the gas pressure is always acting insuch a direction that it tends to seat the valves and I am thereby ableto completely control the gas and pre` vent leakage.

To the under side of the spider 73a I secure valve casings 125, and 126,in oppo-site positions and preferably at right angles to said valvecasings I secure other valve casings 127 and 128, also arranged inopposite positions. The first two valves are alike and the last two arealike but differ from the first only in the number of connections. Eachvalve body has a threaded bar 129, by means of which, and nuts 130, thevalve bodies are secured to the spider 73a. Each valve body has a valveseat 131; a valve 132, provided with a packing 133, adapted to contactwith the valve seat; a spindle 134, for the valve, extending outwardlythrough one end of the valve body; and a spring 135, tending always toclose the valve by reason of its pressure against the shoulder 186. Thevalves 125, and 126, have only a connection at the coupling 137, whilethe valves 127 and 128, have connections at co-uplings 138, and 139, andthis is the only necessary difference between valves 125, 126, and 127128, so that a detailed description of each one is unnecessary.

The valve body 125, is connected with the prima-ry reservoir 10, bymeans of a pipe 140, which is joined at one end to the coupling 48a onthe head 48, and to the coupling 137, on valve body 125. Likewise thevalve body 126, is connected with primary reservoir 9, by means of apipe 141, one end of which is joined to the coupling 50, on the head 51,and the other to the coupling 137, on valve body 126. The purpose ofvalves 125, and 126, is to reduce the primary receptacles 10, and 9, toatmospheric pressure by allowing the gas pressure therein to blow off orsniff, just before water is admitted thereto, preferably by allowing thepressure to escape through the plugs 142. The valve body 127, alsoconnect-s with the primary receptacle 9, by means of a pipe 143,connected to the coupling 139, and preferably by joining with the pipe141 to reduce the number of connections. Likewise the valve body 128, isco-nnected to the primary receptacle 10, by means of a pipe 144, whichconnects at one end with coupling 139, on valve body 128, and preferablyjoins the pipe 140. It will be observed from this that valves 126, and127 are both connected with receptacle 9, and valves 125, and 128, areboth connected with receptacle 10. In addition to the above, valves 127and 128 are connected to a gas supply.v Iy have represented at 145, thegas supply, which mayl be any gas receptacle, preferably one of the longtubes generally used for soda fountains. A pipe 146, connects with thegas supply 145, and also with the coupling 138, on the valve body 127;while a pipe 147, connects with the gas supply and with the coupling 138on the valve body 128.

I have arranged the several valves in a circle around the shaft 70, withtheir stems 134, all directed toward the latter; and with Valves 125,and 126, alternating in position with valves 127 and 128.

On the shaft 7 0, I have arranged a cam 148, which travels with theshaft, in such aw path that it will successively engage and move thespindles on valve bodies 125 to 128, for the purpose of unseating thevalves. With the cam 148, starting from the position shown in Fig. 11,and making one revolution in a clockwise direction the cam will firstpress the stem 134, of valve body 128, thus unseating the valve 132,therein. This will open the gas supply 145, with receptacle 10, holdingit open long enough to allow a supply of gas to enter. As soon as thecam moves away from the spindle this valve will close by reason of itsspring and the pressure of gas behind the valve. After making about aquarter revolution the cam will press in the -spindle 134, of valve body126, unseating the valve therein. This will release any gas inreceptacle 9, and reduce the latter to atmospheric pressure, preparatoryto the reception of the liquid. Another quarter turn of shaft 7 0, willbring cam 148, into contact with the spindle of valve body 127, and thiswill connect the gas supply 145, with receptacle 9. Another quarter turnand the cam will contact with the spindle of valve body 125, and unseatthe valve therein. This will open the receptacle 10, through plug 142,in valve body 125,release gas in receptacle l0 and reduce the same toatmospheric pressure preparatory to the reception of the liquid. Liquidis admitted t-o receptacle 10, and discharged from receptacle 9, atabout the time cam 148, is in the position shown in Fig. 11, whilereceptacle 10, will he emptied of liquid and receptacle 9, filled withliquid while cam 148, contacts with spindle of valve body 126, andbefore it acts on the spindle of valve body 127.

As the greatest gas pressure is at the source of gas supply 145, it willbe observed from the above description that the greatest pressure isalways behind the valves, always tending to seat the valves 127, 128,except when positively opened by the cam. It should also be noted thepressure from receptacles 10, and 9, is behind the valves 125, and 126,and as this is generally above atmospheric pressure the tendency is toseat the valves in valve bodies 125, and 126. Therefore the greatestpressure in each instance acts to seat the valves and thereby I preventthe escape of gas at all times eX- cept when such is intended. This ismaterially aided by providing a separate system of valves for the liquidand gas.

IVe now come to the device for operating the liquid and gas valves. Anupright shaft 70, is sleeved over the spindle 69, of the valve 25, and apin 71, causes the valve to revolve with the shaft 70. The latter at thetop is provided with means by which the several operating devices of`the machinel will impart a partial rotation to the shaft 70, each timethey are operated, and I preferably employ a horizontal gear 72, on thetop of the shaft 70, on which the several operating devices act. Thegear 7 2, is shown as resting on a flange 74, which latter surrounds theshaft 70, and is secured to a spider 73a, supported on the brackets 73,which steady the structure. I have arranged four set-s of operatingmechanisms, disposed radially around the gear 72, equidistant from eachother, though'this number and arrangement may be varied.

I have provided four horizontal shafts 75, 76, 77, and 78, directedtoward the gear 7 2, and for simplicity I have shown the details of theshaft 75, and its connections, and omitted the parts by which the shafts76, 7 7 and 7 8, are operated; and it is to be understood that themechanisms connected with these lat-ter shafts are duplicates of thatconnected with shaft 75. The latter shaft is slotted at 88, and extendsinto a sleeve 79, which is secured by a pin 81, on another shaft 80, inline with the shaft and the latter revolves the shaft 80, by reason of apin 82, through said slot and the sleeve 79. This forms a slip jointbetween the parts and the shaft 80, responds to the rotations of theshaft 75. To the shaft 80, is secured a hub carrying an arm 84, whichrevolves with the shaft and this arm is provided with a pawl 85, pressedby a spring 86, (see Fig. l) into the teeth of a ratchet wheel 87, whichis loose on a reduced portion 89, of the shaft 80.

Preferably formed integral with the ratchet 87, and moving therewith, isa pinion 90, which meshes with the teeth 91, of the gear 72, and thelatter will therefore be responsive to the movements of the ratchet andpinion. rIhe latter are held loosely on shaft by a collar 90a secured tothe shaft. From the above, it will be apparent that when the shaft 75,revolves the shaft 80, and the arm 84, will revolve. The pawl 85,engaging in the teeth of the ratchet wheel 87, will cause the pinion tomove with the shaft 80, and thus the gear 72, will b-e revolved. Buteach of the shaft-s 76, 7 7 and 78, are provided with similar ratchets,pawls, arms and pinions, and the latter all mesh with the gear 72, andthey are all adapted t-o revolve the gear. If one of the pinions ismoving the gear 72, however, the various shafts with which the remainingpinions are connected will not be revolved by reason of the movement ofthe gear 72. If, for instance, the shaft 76, is being revolved itspinion will revolve the gear 72, and the pinion 88, von shaft 80-75 willrevolve therewith, but the pawl 85, of this shaft, will ride over theratchet teeth in this movement and the shaft 80, will therefore be leftidle. So that it will be apparent that the gear 72, may be revolved byeither the shaft 7 5, 76, 77 or 7 8, without disturbing any of theremaining ones. It will also be apparent that one or more of theseshafts may simultaneously operate the gear 7 2, without disturbing theremaining ones.

.These shafts 75, 76, 77, preferably operate the valves which controlthe dispensing of the liquid and are themselves manually operated,through the coin controlled mechanism. rIjhe shafts 75, etc., correspondwit-h the shaft of my said copending application and are preferablyrevolved a partial revolution through the mechanism shown in my saidcopending case, each time the operating handles 92, are operated fromthe eX- 'terior of the cabinet, whenever a purchaser draws a glass ofthe liquid.

On the interior of the casing I have arranged four sets of controllingdevices for dispensing the liquid, but since they are all alike, I willdescribe one set, from which the whole device will be readilyunderstood. Inside the cabinet l, I have arranged a bracket 93, oneplate 94, of which is on a slightly lower plane than the plate 95, andthese plates support various couplings and valves.

There is a pipe 96, running from a common coupling 97, which connectswith the coo-ling coil 7, to each of the vending devices.

At 98, the pipe 96, is bifurcated, one end going to a coup-ling 99, onthe bracket; and the other going to a coupling 100 also mounted on thebracket. The coupling 99, is provided with a valve casing 101, in whichthere is a valve similar to the valve shown in Fig. 18, and it isarranged to be seated by a coil spring in the same manner, and thepressure behindthis valve tends to seat it, whereby the pressureprevents leakage when the machine is idle. The spindle 1011, of thisvalve is directed toward t-he shaft 7 5. The coupling 100, is alsoprovided with a valve casing 105, in which there is a valve in allrespects similar to the one just described, and its spindle 106, alsoprojects toward the shaft 75. The coupling 99, is connected by a pipe107, to one end of a measuring cup 108, which is adapted to mea-sure adefinite quantity of liquid and which is of the piston type. In myapplication for Letters Patent filed on the 12th day of July 1910, andserially numbered, 571557, I showed and described a very etlicientmeasuring cup which may be clearly understood by reference to saidapplication. The purpose of the pipe 107 is to convey the liquid to themeasuring cup whether it be of 'the type shown in my said application orany other type, and to return the liquid after it has been measured, toanother coupling, as

will appear. The coupling 100, is connected by a pipe 109, with theopposite end of the measuring cup 108, whereby liquid is carried to bemeasured and is afterward returned to a dierent coupling fordistribution. The liquids from pipes 107, 109, are measured anddistributed separately. Opposite the couplings 99, and 100, on the samebracket I have arranged other couplings and valves. The coupling 110, isprovided with a valve casing 11, in which there is a valve in allrespects similar to valve 102, and its spindle 112, is also directedtoward the shaft 7 5. The coupling 113, secured to the bracket, isprovided with a valve casing 114C, having a similar valve and thespindle 115, of this valve projects toward the shaft 75. The coupling110, is connected with the pipe 107 by a pipe 116, and therefore inconnection with one side of the measuring cup; while the coupling 113,is connected to the pipe 109, by a pipe 117, and therefore with theother side of the measuring cup. The cou- 118, and 119, respectively,which unite in a common pipe 120, with a discharge spout 121, from whichthe liquid is delivered t0 a drinking glass placed thereunder. Thespindles 104, and 112, are preferably on opposite sides of the shaft 75,and the spindles 106, and 115 are preferably arranged on opposite sidesof the shaft.

The shaft 75, is provided with a sleeve 122, which is secured thereto,and the sleeve has various cams for operating t-he several valvespindles in definite order. I have arranged the shaft 75, to progress inthe saine direction at each operation, which is preferable, and I preferto arrange the cams to act accordingly. On one end of the sleeve 122, Ihave arranged three cams 123, spaced equidistant from each other aroundthe sleeve, which are adapted to press the spindles 104, and 122, in forthe purpose of unseating their valves, but at different times, that is,they are pressed inwardly in alternate relation with regard to eachother. On the other end of the sleeve 122, I have arranged a second setof cams 124, preferably three in number, spaced equidistant around thesleeve; and these cams act upon the spindles 106, 115, for the purposeof pressing them to unseat their respective valves, the return of suchvalves being caused in the four instances by the several valve springsand by the pressure behind the valves. The cams 124, operate on thespindles 106, and 115, alternately similar to cams 123, on theirspindles. The arrangement however, of the cams 123, and 124, isalternate each to the other, so that the valve spindles 104, and 106,will be forced inwardly by their cams in alternate relation to eachother; and the spindles 112, and 115, will be forced inwardly inalternate relation as to each other.

Operation: Let it be assumed that the various partsare in the positionshown in the drawings and that a coin is deposited in the slot 125, andthe handle 92a, shown in the lower part of Fig. 2, is turned to theright as far as it will go. This will turn the shaft 75, and sleeve 122,a partial revolution. One of the cams 123, will be moved away from thevalve stem 104, causing this valve to close, and the connection betweenthe cooling coil 7, and the one side of the iiieasuring cup throughwhich the pipe 107, con nects. At the same time, one of the cams 123,forces the spindle 112, inwardly and opens the valve in casing 111;thereby opening the pipe 116, which connects with the side of themeasuring cup which has just been shut off from the liquid supply, tothe spout 121, under slot 125; when the liquid in the measuring cupconnected with this set 2 of mechanisms will discharge itsl contentsinto a tumbler placed under it. At the same time, one of the cams 124,forced the spindle plings 110, and 113, are connected by pipes 106,inwardly uiiseated the valve in casing 105, and connected the coolingcoil 7, up

with the opposite side of the measuring cup 108, through the pipe 109.The liquid enter ing the right side of the cup in F ig. 1, forces over apiston (as will be understood in my pending application Serial No.571,557 iilcd July 12th, 1910) and forces the liquid on the oppositeside of the piston out through pipe 1116, which is connected with thedischarge spout. At the same time the measuring` cup is filled withliquid from pipe 109, and rei,mains s0 until the next succeedingoperation vof the handle 92a. Another of the cams 124, jmoves away fromthe spindle 115, thereby releasing the valve in casing 114, and allowing it to be seated by its spring and the pressure, in which conditionit will remain until :the next operation of this particular mechanism.'discharge pipe 117, running from pipe 109,

The closing of valve 114, closes the and therefore closes the dischargeconnecftion from that side of the measuring cup to ,which the supply hasjust been connected. In this manner the cooling coil which supv'pliesthe aerated liquid to the measuring cup is disconnected from one side ofthe cup and connected with the other: and the discharge spout isdisconnected from that side .of the measuring cup to which the supply'is connected and is connected with that side of the cup from which thesupply is disconnected; and this operation is accomplished wit-hout theuse of ground-invalves, but instead, with valves in which the pressuretends to seat the valves at all times: so that there will be no leakagefrom the valves when closed, either of liquid or gas, and nodeterioration of the mixture, at this point. `Vhen the handle 92a isoperated again, the

-plied to that side from which the liquid was withdrawn in thepreviously described operation. The liquid is thus supplied to and-withdrawn from, opposite sides 0f the measuring cup alternately. If themachine remains idle for any considerable time there will be no leakageor deterioration. These opera,- tions maybe repeated as often as desiredand liquid will be dispensed at each operation.

Since there are valves, a measuring cup, supply, and discharge, forevery operating or coin mechanism, all may be operated simultaneously,or in any order, as each dispensing mechanism operates independently.

The movement of the shaft 7 5, in the above operation may be followedthrough the other mechanisms. The partial rotation lof shaft 75, wastransmitted through the connected shaft 80, to the pawl arm 84. Themovement of the latter caused, by means of the pawl 85, the ratchetwheel 87, to par'- tially revolve: and since the pinion 88, is partthereof, the movement is transmitted through the pinion to the4 largegear 72. The latter was in this manner caused to revolve a slightamount; and consequently its shaft 70, and the valve 25. This movementof the gear 72, may be repeated by the successive operations of thehandle 92, or by any of the other handles operating in any orderwhatsoever. 1f two of the operating handles are operated at the sametime and speed they will both revolve the gear 72, at the same time andno conflict will arise. If one operating handle is so turned while asecond is being operated, so that it turns its shaft at a greater speedthan the second one, then the faster one will revolve the gear 72. Thepinion and ratchet wheel connected with the slower moving` shaft willcause such pinion to escape under the pawl of such shaft, so that theslower moving shaft will not be turned from the gear 72. Otherwise thecoin mechanism of the slower moving shaft might become disarranged inposition, and the burdens of both operations might fall upon the fastmoving shaft, which results 1 prefer to avoid. The operations of thevarious dispensing mechanisms acting on the gear 72, will finally causea revolution of the shaft 70, and in fact they will cause successiverevolutions thereof. Let it be assumed that the move-ment of the gear72, be clockwise as viewed from the top as in Fig. 2; while the valve25, is in the position shown in Fig. 6, the primary receptacle 10, isconnected with the source of liquid supply, through pipe 19, connection23, ports 24, and 26, in the valve 25, the port 27, in the connection28, and through the pipe 31. During this position the primary receptacle10, is disconnected from the reservoir, and it is therefore receivingits supply of liquid. When the liquid is coming into receptacle 10,through pipe 31, the relief valve 66, is unseated allowing the air orgas in receptacle 10, to be discharged to admit the incoming liquid; butwhen the liquid reaches the float 64, it will raise the latter, seat thevalve 66, and stop the ingress and prevent the liquid from escaping.While this condition exists in the receptacle 10, a different conditionexists in receptacle 9. The latter at this time is connected at thebottom with the reservo-ir through the pipe 58, the port 53, in coupling54, through the port 52, in the valve 25, and the port 8, and the liquidfrom this receptacle is discharging or has discharged against the plate4, causing it to break up into sprays and more readily mix with the gas.It may be restated, that while the replenishing operations are takingplace in the gas and liquid volved a slight extent the port 26, in theliquid valve 25, will gradually move away from the port 27, unt-il thereceptacle 10, is finally disconnected from the liquid supply, thereceptacle by this time having been filled with liquid to such an extentthat its float 64, is raised by the liquid until t-he valve 66, isseated. Just preceding the opening of port` 55, the cam 148, on theshaft 70, begins to act upon the spindle of valve casing 128, to unseatthe valve therein. As soon as cam 148, progresses far enough to unseatthis valve the receptacle 10, will become connected with the source ofgas supply through pipes 147, 144, and 140. The gas will enter throughconnection 48a into the head 48, and this will supply the recep taclel0, with. .enough gas to carbonate the amount of water in thisreceptacle; and `it will also furnish the necessary pressure to forcethe liquid therefrom into the reservoir as the receptacle is connectedtherewith. Vhen the cam 148, disengages from the spindle of valve casing128, the valve therein will close under the action of its spring and thegreater gas pressure behind it.

When the liquid port 27, leading to receptacle 10, was closed, the port52, in valve 25, was also moved away from port 53, and thereby thereceptacle 9, was disconnected from the reservoir. While the receptacle9, is thus disconnected from both the liquid supply and the reservoirthe dispensing mechanisms continue to revolve the shaft 70, until thecam 148, finally acts upon the spindle in valve casing 126, and finallyunseats the valve therein. This will open the pipe 141, running fromreceptacle 9, and any residual pressure in the latter will be vented orsniffed through the open plug 142, on valve casing 126; reducingreceptacle 9, to atmospheric pressure. This is for the purpose ofpermitting the subsequent ingress of liquid into this receptacle andalso to release such gas as has not been mixed with the liquid or whichdid not follow the latter into the reservoir; and also to exhaust anyair which the gas separated or displaced from the liquid while in thereceptacle9. When the pressure in receptacle 9, is thus released,following the exit of the liquid therefrom there will be nothing to holdup thef float 64, in the head 51, and therefore the latter will drop bygravity, unseating the valve 66, which will remain unseated until thesubsequent entry of a new supply of liquid. Further movement of theshaft 70, completing a half turn from the described starting position,will bring about another change of conditions. When this point isreached the port 26, in valve 25, will come to register with the port29, and receptacle 9, will be opened with the liquid supply throughpipes 23, and 33, and as the vent valve 66, is unseated and thereceptacle 9, is at atmospheric pressure liquid will flow thereinto.yReceptacle 9, will become filled with liquid until the latter raises thefloat 64, and seats valve 66, when further ingress will cease. At thistime it is to be remembered that receptacle 9, is disconnected from thereservoir. At the same time that the above change occurred, the port 52,came to register with port 55, and thereby receptacle 10, was openedwith the reservoir, through pipe 57, and port 3. The liquid in thisreceptacle thereupon emptied into the reservoir, striking the plate 4,which causes it to spray. The gas previously admitted to this receptacleforces the liquid, now partially carbonated, into the reservoir, and atleast a 'portion of the free gas will follow the liquid into thereservoir to furnish the latter with a suflicient supply of gas tocontinue the aeration. When the liquid in receptacle 10, recedes, it nolonger supports the float 64, in the top 48, but the gas pressure willbe suflicient to support the float until the water is discharged fromreceptacle 10, into the reservoir. Otherwise the gas would escape notonly from the receptacle 10, but also the reservoir at this moment. Thereservoir 10, at this time it will be remembered is disconnected fromthe liquid supply.

l/Vhen the shaft 70, gradually turns beyond the half revolution the port26, will move away from port 29, to disconnect ret cept-acle 9, from theliquid supply and cam 148, will come to act upon the spindle in valvecasing 127. This latter will unseat the valve in this casing and as aconsequence the receptacle 9, will be opened with the gas supplyvthrough pipes 146, 143, and 141. Gas will now flow into the receptacle9, to miX with the liquid therein and provide the propelling force forexpelling the water. From this last position the shaft 70, will proceedanother quarter turn, when the cam 148, will press in the spindle inValve casing 125, and unseat the valve therein. This will open the pipe140, leading from receptacle 10, and any residual pressure in the latterwill blow off through plug 142, in casing 125, and reduce thisreceptacle to atmospheric pressure. The next change will take place whena partial revolution of shaft 70, brings the liquid ports to register asin Fig. 6, which is the Iwithdrawn for the 22, drinks.

position with which the description of the above operations began. Theoperations above described will be repeated at each revolution of shaft70, whether the latter operates continuously orleven when considerabletime elapses between partial revolutions and in n0 case will the mixturebecome affected by the improper release of gas nor will the gas leakinto the atmosphere or into the water main. The gas which passes with orbehind the liquid when receptacles 9, or 10, are emptying into thereservoir not only supplies the latter with gas to continue aeration,but also to furnish the propelling force for driving the liquid from thereservoir to the dispensing` faucets.

As shaft 70, is operated by the manually operated device the reservoir.is replenished with liquid in accordance with the amount of liquidwithdrawn therefrom because at each operation of one of the coincontrolled mechanisms the shaft 70, is advanced one unit of motion.There is no point reached where the replenishing operation ceases to beoperative as is the case in the balanced valve system hereinbeforereferred to. By employing the complete arrangement as herein shown, asingle replenishing mechanism will suiiice for the several distributing.devices and each of the latter will effect the operation of the former.In practice I arrange 44, teeth on the gear 72, so that each time 22,

drinks have been withdrawn from the reservoir one of the primaryreceptacles will discharge its contents into the reservoir, which willbe sufficient to replace the quantity It will be understood that asingle primary receptacle could be used by simply omitting the other andits connections, but I prefer to use a plurality thereof and operatethem in alternate relation because the whole arrangement is then moresuccessful in its construction and operation.

In the event the reservoir is so completely filled at a time when eitherprimary recepitacle is connected therewith to discharge its contentsinto the reservoir, that there is inlsulhcient space to receive any orall of the contents of the primary receptacle at this time, nodifficulty will arise in the operation of the machine. In such event,part or all of the contents of the primary receptacle failing todischarge will remain therein, until the same primary receptacle isagain connected with the liquid supply, when such receptacle willreceive either no fresh supply of liquid or only enough in addition towhat is left remaining therein to fill the primary receptacle. Fromthence on the machine will operate as before without change.

I have produced a machine which is automatic in the sense that the forceof the gas is used to propel the liquid or mixture through t-he machine;that the supply in the reservoir is replenished in accordance with theamount drawn off; and by controlling the replenishing operation by thedispensing mechanism greater results are not only obtained but themechanism is made simpler and more positive. All parts are accessibleand the entire machine may be confined within a cabinet of reasonableproportions. Aside from the above the machine is so constructed thatthere are no leakages and therefore no deterioration of the mixture,even though the machine remains idle for a considerable time betweenoperations.
